Abstract

Performance at different bit rates of phase modulated signals for star, tree and mesh optical network topologies is evaluated using Raman-EDFA hybrid optical amplifier. Consideration of BER is made to investigate the number of users supported. Evaluation of the number of users supported is carried out at -40dBm input signal power. Hybrid Raman-EDFA amplifier is placed as a post amplifier. In all these three topologies, the signals are generated at 90o phase deviation. The channel spacing is taken as 0.1 THz with 1MHz line width. Mesh topology supports more number of users than other topologies at 10Gbps and 20 Gbps. At the bit rate of 10 Gbps within acceptable BER range, Mesh topology supports 8 number of users whereas star topology supports 5 users and tree topology supports 4 users. At 20Gbps within acceptable BER range, Mesh topology supports 6 users whereas tree topology supports 4 users and star topology supports 2 users. No topology is able to support any user at 30 Gbps.
